The antitussive actions of the drug Ru 20201 given as an aerosol to cats.

The effect of the drug Ru 20201 (1,2,3,4,4a,9b-hexahydro,-8,9b-dimethyl-4-[3-(4-methylpiperazin-1-yl)propionamido]dibenzofuran-3-one upon mechanically-evoked cough from the laryngopharyngeal and tracheobronchial areas in nine unanaesthetized cats has been examined. Inhalation of 2 ml of an aerosol of a 10% solution in water suppressed coughing for 30 min. The effect was greatest on the number of cough efforts. The expiratory component of cough was suppressed more than was the inspiratory one. The effect was greater on cough from the laryngopharyngeal than from the tracheobronchial area.
